Calgary led 25-10 early in the fourth after Arbuckle’s second short-yardage touchdown of the game and a Paredes convert.

Johnson, back in B.C.’s lineup after a July 14 ankle injury, scored a five-yard rushing touchdown late in the third.

A 57-yard punt return by B.C. running back Travon Van early in the quarter gave the Lions the ball on Calgary’s 21-yard line.

B.C. failed to capitalize on that field position, however, and turned the ball over on downs after three consecutive incomplete passes by Lulay.

Calgary led 17-3 at halftime in front of an announced crowd of 25,075 at McMahon Stadium.

Starting from Calgary’s eight-yard line late in the first half, Mitchell marched the Stampeders offence downfield with a 62-yard pass to Jorden, a 19-yard throw to DaVaris Daniels and a 22-yard toss to Marken Michel.
